Application filed November 36, 1925'. "serial No. 72,297.

This invention relates to oil burners and more'especially to the type of burner that is commonly. known as wickless in which there is an annular fuel well having an asbestos 5 ring, the wellbeing raised or lowered, to

change the level of the oil therein in accordance with whether it is desired to. have the burner lighted or not.

It isone of the objects of the invention to provide an improved mechanism for supporting and raising and lowering the well and also to provide convenient means whereby the fuel supply passages may be readily cleaned.

features of novelty will be apparent from the following description taken in connection with the accompanying drawings, of

' which:

side walls of the well, the well being preferably stamped out of sheet metal.

1.0, is a tubular support 16 which is secured to the wall 15 at the diametrically opposite points 17 and 18, by welding, brazing or in any other suitable manner. One end of the tubular member l6 is preferably flattened and closed by welding or in any other suitable manner as indicated at 19. The other endof the member 16 is inclined upwardly, adjacent the outer side of'the well 10, as indicated at 20, andis provided with a removable, closure 21, which may be in the form of a screw or-any other preferred type. The upper end of the extension 20 is above the highest level to which the oil'rises in the well 10 so that there will be no -possibility of the oil overflowing from-this extension. A port 22 is provided for the purpose of supplying oil from the'member 16 to the interior of the well 10. .A vertically extending pipe 23 is welded 5 or otherwise secured to the lower side of the tubular member 16 and slidably ar- Other objects of the invention and the;

lower edge of the well 10 is closed by a wall 15 which is usually made integral with the ranged a supply pipe 2 1, astufling box 25 being provided at "the upper'end of the "pipe 24 for the purpose of. preventing leak age of 011; A vertically arranged rack 26" is welded or brazed to the flattened portion '27, of the tubular member 16, and extends into a guiding frame 28 which is secured to the pipe 24 and to the horizontal header 29, on whichthe pipe 24 ismounted. The

frame 28 carries a shaft30 on whichthere is a sector gear 31, which meshes with the well 10 and the chimney 14, maybe raised and lowered at will, by rotating'the shaft rack 26 so that the rack, together with the 30. The rack 26 also serves as a guide which assists in maintaining the well '10 'and' the parts, associated therewith, in their proper-positions.

The extension '20'prov1des a convenlent means by which thei'fuel supply passages maybe cleaned. For this-purpose, ,1tf1s only necessary to removethe closure mem-f ber 21 and insert a wire into the extension '20. When the ring llis remove d from the well, the port 22 is also accessible for clean-,3

ing and any foreign material found in the through the extension 20. 3 g
